First, welcome, and thanks for reading the "how to fish" thread -- you're already ahead of the game!
Second, the style of photos are very familiar to some of us here (Closer from Japan, right?) and usually represent pretty good value. I've personally bought at least half a dozen from them, and regret none. They are high volume, and regularly have sales, so don't feel you have to rush. Which leads me to...
Third: nice choice for a first vintage! You can tie yourself up in knots getting the "perfect" watch, but if it speaks to you, do it.
Finally: these two are on my radar from the same seller. Both are less common 36mm sizes, very similar price, variations on a theme really. I don't mean to confuse, but just to reinforce there are good deals around (especially with weak Yen at the moment).
Again, welcome to the forums!
